Good news! From Dale at Metro:

We noticed…that you are interested in what became of the bus shelters in the photos…next to the Douglas Truth Library. The shelters were removed last week for refurbishing, and will be re-installed this week. All Metro bus shelters are pulled every 7 to 8 years, repainted and reinstalled w/new windows, walls, and translucent roofs. When a shelter is pulled it is usually replaced the same day or within a few days after the removal.

The terra cotta tile artwork that was in these shelters, will need additional restorative work before returning to the shelters, but should be re-installed in the shelters sometime this fall.

I am relieved to know that my shelters will soon return. Now if only we riders were provided with warnings before our shelters were removed. Something as simple as a paper rider-alert sign near the schedule would have eliminated a lot of confusion.
